Circularly averaged radial profiles computed in concentric 0.3″-binned annuli are shown for (i) the stacked PSF of our ALMA observations (black solid line for galaxies in our sample, and black dashed line for ALPINE continuum-detected galaxies), (ii) the stacked FIR continuum of 23 ALPINE continuum-detected galaxies (mostly belonging to the high-SFR group, see text; orange squares), and (iii) the stacked maps of [C II] cores ([ − 200 :   + 200] km s⁻¹) for galaxies in the low-SFR (green squares) and high-SFR (blue square) groups. Error bars are indicative of the ±1σ dispersion of fluxes in each annulus, while the thin dashed lines represent the Poissonian noise associated with the radial profiles¹⁰.
